expect.not.arrayContaining(array) matches a received array which does not contain all of the elements in the expected array. That is, the expected array is not a subset of the received array.

It is the inverse of expect.arrayContaining.

describe('not.arrayContaining', () => {
  const expected = ['Samantha'];

  it('matches if the actual array does not contain the expected elements', () => {
    expect(['Alice', 'Bob', 'Eve']).toEqual(
      expect.not.arrayContaining(expected),
    );
  });
});
